So installed berk test pipes and an invidia n1 exhaust awhile ago and i’m throwing CEL. I bought two new o2’s since the install and cleared the ecu but i’m still throwing CEL. If i bought a megan o2 delete extra for each TP could that fix the CEL? or would the o2’s be to far now?

You will need the O2 extenders for the primary sensors. I ordered mine from Z1 for my AAM test pipes. Going on a year with no problems.

With the berk test pipes already having the “o2 bung” will the extender make it to far?

We have emissions testing in WA but i’d just pay for the waiver, i’m not worried about emessions just having the light off to ease my paranoid mind. Trying to get a tune would be the most expensive route but probably worth it

Cool! ill probably grab the Z1 extenders and see if the problem goes away if not i’ll probably buy the electrical o2 delete
